Meaning of Telecommunications
What are Telecommunications:
Telecommunications are the remote transmission of information data by electronic and / or technological means.
Information data is transported to telecommunications circuits by electrical signals.
A basic telecommunication circuit consists of two stations, each equipped with a receiver and a transmitter, which can be combined to create a transceiver.
A telecommunications network consists of multiple interlinked transmitter and receiver stations that exchange information. The widest and most well-known network is the Internet. Other smaller networks are telephone networks and private radio broadcasts.
In a telecommunications system, cables, fiber optics or electromagnetic fields are generally used for the transmission of telecommunication signals. The areas free of data transmission and reception by electromagnetic fields are known as Wireless and Radio.
History of telecommunications
Telecommunications, as we know it today, had its first turning point in the year 1800 when Alessandro Volta invented the electric cell or electric battery. The next great advance in this area was the electromagnetic telegraph developed by Samuel Morse in 1835 and then the expansion of the telephone in 1876 when Alexander Graham Bell obtained his patent in the United States. From there, the advance in telecommunications grew unchecked.
